[0011] Preferably, the side box frame is fixedly installed on one side of the machine body. The upper part of the side box frame is a box structure. The side box frame is used to store adhesive. The size of the side box frame is larger than the size of the board. Multiple feeding rollers are rotatably fitted inside the side box frame. The feeding rollers are uniformly distributed in a concave structure. The top of the feeding roller's conveying track is at the same horizontal height as the conveying track of the conveyor belt.

[0015] Compared with the prior art, the present invention provides a UV-assisted impregnation and coating device for the production of high-frequency and high-speed copper-clad laminates that can be photocured, which has the following beneficial effects: 1. This UV-assisted impregnation and coating device for the production of high-frequency, high-speed photocurable copper-clad laminates involves first feeding the board into a side rack, where it undergoes impregnation. After impregnation, the next board enters the side rack, pushing it into the machine body. The UV lamps are then turned on, irradiating the board with ultraviolet light to cure the adhesive. When the accumulated cured layer on the UV lamps needs to be cleaned, a scraper is used to move along the UV lamps, cleaning them as needed or periodically. This ensures the UV lamps' irradiation efficiency and improves the device's processing efficiency.

[0016] 2. The UV-assisted impregnation and coating device for the production of high-frequency and high-speed photocurable copper-clad laminates uses a top cover to cover the adhesive in the side chamber, preventing the adhesive from being directly exposed and drying and curing quickly. This effectively extends the external use time of the adhesive and improves the stability of the device operation.

[0017] 3. The UV-assisted impregnation and coating device for the production of high-frequency and high-speed photocurable copper-clad laminates can be controlled by the signals detected by the detector. This allows the device to not only run the scraper for cleaning when needed, but also to run the scraper again after a certain period of time after each signal is generated by the detector. This makes the cleaning of the cured layer a periodic action, ensuring that the UV lamp can maintain good irradiation efficiency for a long time. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a UV-assisted impregnation and coating device for the production of high-frequency and high-speed copper-clad laminates that can be photocured.

[0022] Example 1, a typical implementation of this application, such as Figure 1 As shown, a UV-assisted impregnation and coating device for the production of high-frequency and high-speed photocurable copper-clad laminates includes a body 1, a coating and curing mechanism 2 disposed on the body 1, and an auxiliary mechanism 3 disposed on the coating and curing mechanism 2. The coating and curing mechanism 2 includes a UV lamp tube 213 and a side box frame 214. The UV lamp tube 213 is disposed inside the body 1 and performs UV curing treatment on the board. The side box frame 214 is disposed next to the body 1 and performs impregnation treatment on the board. The board after impregnation in the side box frame 214 is conveyed below the UV lamp tube 213. The auxiliary mechanism 3 includes a scraper 31, which is disposed next to the UV lamp tube 213. The scraper 31 is moved to scrape the UV lamp tube 213.

[0023] When using this invention: The sheet material is first fed into the side box rack 214, where it undergoes impregnation with adhesive. After impregnation, the next sheet material from the rear enters the side box rack 214, pushing the impregnated sheet material into the machine body 1. The UV lamp tube 213 is then turned on, emitting ultraviolet light to irradiate the sheet material, causing the adhesive on the sheet material to complete UV curing. When it is necessary to clean the cured layer accumulated on the UV lamp tube 213, the scraper 31 is used for translation. The scraper 31 moves along the UV lamp tube 213, cleaning the UV lamp tube 213. This allows for necessary or periodic cleaning of the accumulated cured layer, ensuring the light irradiation efficiency of the UV lamp tube 213 and improving the processing efficiency of the device.

[0024] Example 2, as Figures 2-7 As shown, the difference from the above embodiment is that the adhesive curing mechanism 2 also includes a conveyor roller 21. Multiple conveyor rollers 21 are rotatably fitted inside the machine body 1. The conveyor rollers 21 are horizontally arranged and evenly distributed on the machine body 1. A conveyor belt 22 is tensioned on the entire conveyor roller 21. The conveying length of the conveyor belt 22 is adapted to the length of the machine body 1. Openings are provided on both sides of the machine body 1. The openings on both sides of the machine body 1 are adjacent to the two ends of the conveyor belt 22 respectively. The width of the conveyor belt 22 is greater than the width of the board.

[0025] Furthermore, a stepper motor 23 is fixedly installed inside the machine body 1. The stepper motor 23 is located below the conveyor belt 22. A power gear 24 is rotatably fitted inside the machine body 1. The power gear 24 is adjacent to the stepper motor 23 and is poweredly connected to the stepper motor 23. A driven gear 25 is rotatably fitted inside the machine body 1. The driven gear 25 is adjacent to the conveyor roller 21 and is poweredly connected to a single conveyor roller 21. The driven gear 25 and the power gear 24 are located on the same vertical plane. A chain 26 is tensioned on the driven gear 25 and the power gear 24.

[0026] Furthermore, an air inlet pipe 27 is fixedly installed at the center of the top of the body 1. The air inlet pipe 27 is connected to the body 1. A first fan 28 is fixedly installed on the body 1. The exhaust end of the first fan 28 is connected to the air inlet pipe 27. The air inlet end of the first fan 28 is connected to the air supply system.

[0027] Furthermore, exhaust pipes 29 are fixedly installed on both sides of the top of the body 1, and the exhaust pipes 29 are connected to the body 1. Second fans 210 are fixedly installed on both sides of the top of the body 1. The air inlet of each second fan 210 is connected to each exhaust pipe 29, and the air outlet of the second fan 210 is connected to the exhaust system.

[0028] Furthermore, both the air supply system and the exhaust system are part of the air supply system installed in the ceiling of the production workshop. The air supply system supplies air to the device through the air duct, and the exhaust system sends the exhaust gas discharged from the device into another air duct for discharge. The air supply system and the exhaust system included in the air supply system are existing technologies and will not be described in detail here.

[0029] Furthermore, multiple air-concentrating hoods 211 are fixedly installed inside the machine body 1. The air-concentrating hoods 211 are located above the conveyor belt 22 and are evenly distributed inside the machine body 1. A reflector 212 is fixedly installed at the bottom of each air-concentrating hood 211. The size of the reflector 212 is smaller than that of the air-concentrating hood 211, so that the air-concentrating hood 211 covers the reflector 212. The reflector 212 is used to reflect and concentrate ultraviolet light. A UV lamp tube 213 is installed inside each reflector 212. The length of the UV lamp tube 213 is adapted to the length of the reflector 212. Both ends of the UV lamp tube 213 are snapped into the lamp holder on the reflector 212. The coverage area of ​​the UV lamp tube 213 after being concentrated by the reflector 212 is adapted to the conveying range of the conveyor belt 22.

[0030] Furthermore, a side box frame 214 is fixedly installed on one side of the machine body 1. The upper part of the side box frame 214 is a box structure. The side box frame 214 is used to store adhesive. The size of the side box frame 214 is larger than the size of the board. Multiple feeding rollers 215 are rotatably fitted inside the side box frame 214. The feeding rollers 215 are uniformly distributed in a concave structure. The top of the conveying track of the feeding rollers 215 is at the same horizontal height as the conveying track of the conveyor belt 22. When the board enters the side box frame 214, the board is conveyed into the side box frame 214 by the feeding rollers 215 for adhesive impregnation.

[0031] Furthermore, a guide plate 216 is fixedly installed inside the side box frame 214. The guide plate 216 is located between adjacent feeding rollers 215. The guide plate 216 is used to guide the plate at the bottom end of the concave structure of the feeding rollers 215 to export the plate onto the conveyor belt 22. A top cover 217 is fixedly installed at the top of the side box frame 214. The length of the top cover 217 is adapted to the length of the side box frame 214. The top cover 217 is adjacent to the opening on one side of the machine body 1, so that the top cover 217 covers the side box frame 214. The end of the top cover 217 and the side box frame 214 are open ends, so that the plate enters the side box frame 214 from the position between the end of the top cover 217 and the side box frame 214.

[0032] During UV curing, the conveying system feeds the sheet material into the side box frame 214. The sheet material falls at the bottom of the concave structure of the feeding roller 215, where it undergoes adhesive impregnation. After the adhesive impregnation, the next sheet material enters the side box frame 214, pushing the impregnated sheet material, which is then guided by the guide plate 216 into the machine body 1. The impregnated sheet material in the machine body 1 falls onto the conveyor belt 22. The stepper motor 23 is then started, driving the power gear 24 to rotate. The power gear 24 drives the chain 26 to rotate, which in turn drives the driven gear 25 to rotate. The driven gear 25 then drives the conveyor belt... Roller 21 rotates, and conveyor roller 21 drives conveyor belt 22 to rotate, so that conveyor belt 22 carries the glue-impregnated board to the bottom of UV lamp tube 213. Then UV lamp tube 213 is started. UV light emitted by UV lamp tube 213 is reflected and focused by reflector 212, so that UV light shines on the glue-impregnated board on conveyor belt 22, so that the glue on the board is UV cured. At the same time, the first fan 28 and the second fan 210 are started. The first fan 28 sends air into the air inlet pipe 27, so that the airflow is blown into the machine body 1 and blown onto the board through the air concentrator 211. The second fan 210 sends air into the exhaust pipe 29, so that the airflow in the machine body 1 is drawn into the exhaust pipe 29, and the generated waste gas is discharged.

[0033] Example 3, as Figures 8-11 As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a fine screw 32. A scraper 31 is slidably fitted inside the reflector 212. The lower end of the scraper 31 has an annular structure, and the annular part of the scraper 31 is sleeved on the UV lamp tube 213. The size of the annular structure of the scraper 31 matches the cross-sectional size of the UV lamp tube 213. The upper end of the scraper 31 has an arc-shaped structure, and the arc-shaped part of the scraper 31 matches the shape of the inner wall of the reflector 212. The arc-shaped part of the scraper 31 fits against the inner wall of the reflector 212. A fine screw 32 is rotatably fitted inside the reflector 212. The length of the fine screw 32 matches the length of the reflector 212. The fine screw 32 passes through the middle of the scraper 31, and the fine screw 32 is threadedly fitted with the scraper 31. A servo motor 33 is fixedly installed on each reflector 212, and each servo motor 33 is poweredly connected to each fine screw 32.

[0034] Furthermore, the lower end of the annular structure of the scraper 31 can be configured as a rotating and opening arc-shaped part, so that the arc-shaped part can be rotated and opened to facilitate the removal of the UV lamp tube 213. In use, the arc-shaped part is re-engaged on the annular structure of the scraper 31.

[0035] Furthermore, a detector 34 is fixedly installed inside each reflector 212. The detector 34 is located at the end of the movement trajectory of the scraper 31. The detector 34 and the servo motor 33 are distributed on both sides of each reflector 212. The detector 34 and the servo motor 33 are connected by signal. When the scraper 31 moves and touches the detector 34, the detector 34 controls the servo motor 33 to reverse.

[0036] Specifically, the machine body 1 is equipped with a controller, that is, an integrated controller that includes a touch screen and other control structures. The detector 34 is connected to the integrated controller, and the integrated controller is electrically connected to the servo motor 33. In this way, the detector 34 detects the signal and then controls the servo motor 33 to run in reverse.

[0037] When it is necessary to clean the UV lamp tube 213 and the reflector 212, the servo motor 33 is started. The servo motor 33 drives the fine screw 32 to rotate. The fine screw 32 drives the scraper 31 to move inside the reflector 212, so that the scraper 31 scrapes and cleans the cured layer on the UV lamp tube 213 and the reflector 212. When the scraper 31 moves and touches the detector 34, the detector 34 controls the servo motor 33 to run in reverse through the integrated controller, so that the servo motor 33 drives the scraper 31 to move back to its original position.

[0038] Working principle of the invention: The sheet material is first fed into the side box rack 214, where it undergoes impregnation with adhesive. After impregnation, the next sheet material from the rear enters the side box rack 214, pushing the impregnated sheet material into the machine body 1. The UV lamp tube 213 is then turned on, emitting ultraviolet light to irradiate the sheet material, causing the adhesive on the sheet material to complete UV curing. When it is necessary to clean the cured layer accumulated on the UV lamp tube 213, the scraper 31 is used for translation. The scraper 31 moves along the UV lamp tube 213, cleaning the UV lamp tube 213. This allows for necessary or periodic cleaning of the accumulated cured layer, ensuring the light irradiation efficiency of the UV lamp tube 213 and improving the processing efficiency of the device. During UV curing, the conveying system feeds the sheet material into the side box frame 214. The sheet material falls at the bottom of the concave structure of the feeding roller 215, where it undergoes adhesive impregnation. After the adhesive impregnation, the next sheet material enters the side box frame 214, pushing the impregnated sheet material, which is then guided by the guide plate 216 into the machine body 1. The impregnated sheet material in the machine body 1 falls onto the conveyor belt 22. The stepper motor 23 is then started, driving the power gear 24 to rotate. The power gear 24 drives the chain 26 to rotate, which in turn drives the driven gear 25 to rotate. The driven gear 25 then drives the conveyor belt... Roller 21 rotates, and conveyor roller 21 drives conveyor belt 22 to rotate, so that conveyor belt 22 carries the glue-impregnated board to the bottom of UV lamp tube 213. Then UV lamp tube 213 is started. UV light emitted by UV lamp tube 213 is reflected and focused by reflector 212, so that UV light shines on the glue-impregnated board on conveyor belt 22, so that the glue on the board is UV cured. At the same time, the first fan 28 and the second fan 210 are started. The first fan 28 sends air into air inlet pipe 27, so that the airflow is blown into machine body 1 and blown onto board through air concentrator 211. The second fan 210 sends air into exhaust pipe 29, so that the airflow in machine body 1 is drawn into exhaust pipe 29, and the generated waste gas is discharged. When it is necessary to clean the UV lamp tube 213 and the reflector 212, the servo motor 33 is started. The servo motor 33 drives the fine screw 32 to rotate. The fine screw 32 drives the scraper 31 to move inside the reflector 212, so that the scraper 31 scrapes and cleans the cured layer on the UV lamp tube 213 and the reflector 212. When the scraper 31 moves and touches the detector 34, the detector 34 controls the servo motor 33 to run in reverse through the integrated controller, so that the servo motor 33 drives the scraper 31 to move back to its original position.
